Walk down a typical British high street and count the empty units. Then drive to the retail park on the edge of the same town and try to find a vacant one. That contrast is now the most important structural story in UK retail property. Retail park vacancy has fallen close to record lows while high street footfall keeps sliding, and the money has followed: out-of-town schemes took 42 per cent of all UK retail Investment in 2025, and landlords who bet on them are reporting near-full occupancy and rising rents. The high street’s problem is not simply that shoppers stopped spending. A large chunk of them relocated, and the shops went with them.

The occupancy gap that changed everything

Savills research published in June 2026 put headline retail park vacancy at 4.3 per cent, falling to 1.8 per cent once long-term vacant and obsolete units are stripped out. Less than a year of Supply remains, and 91 per cent of retailers are renewing leases rather than moving on, choking off space for anyone trying to expand.

CBRE’s 2026 UK retail outlook puts retail park vacancy at 6.1 per cent on a broader measure, and forecasts retail parks will deliver the strongest five-year rental growth of any retail format at 4.7 per cent a year.

Only about 1 per cent of additional retail park space has been built in the past five years. Planning is restrictive, values sit below replacement cost in many locations, and the pipeline is thin. Supply is fixed while Demand climbs.

Footfall is voting with its feet

BRC-Sensormatic figures for July 2026, covering 5 July to 1 August, showed total UK footfall down 2.1 per cent year on year. High streets fell 3.8 per cent and shopping centres 1.4 per cent. Retail parks were the only format to grow, up 1.2 per cent.

That is not a one-month quirk. Free parking, single-trip convenience, click-and-collect and lower rents per square foot have made retail parks the default for bulky, planned and grocery-adjacent shopping.

Where the money is going

UK retail investment totalled £5.83bn in 2025, according to Knight Frank — down 17 per cent on 2024 and 8 per cent below the ten-year average. Yet retail Warehousing took 42 per cent of that, with out-of-town transaction Volume alone reaching roughly £2bn and twelve-month returns of about 9.8 per cent.

The largest retail Warehouse deal of 2025 illustrates the pricing. US-listed Realty Income paid £157.25mn for County Oak Retail Park in Crawley and Solihull Retail Park at a 6.45 per cent yield, buying from Tritax Group and Delancey. That looks generous against prime London offices, with rental growth attached.

The landlords making the call

British Land (LSE: BLND) is the clearest pure-play bet. For the year to 31 March 2026 it reported retail parks at 99 per cent occupancy, second-half leasing struck 6.3 per cent ahead of previous passing rent, and £94mn of retail acquisitions — principally three retail parks — at a 7.2 per cent topped-up net initial yield. Across its Retail and London Urban Logistics segment, values rose 2.7 per cent and estimated rental value grew 3.6 per cent, lifting EPRA net tangible Assets to 590p a share. Chief executive Simon Carter said availability of high-quality space in the right locations is “near record lows”.

LondonMetric Property (LSE: LMP) reached a £7.6bn portfolio at 31 March 2026, 98 per cent occupied with a 17-year weighted average Lease term. Convenience assets, including supermarket-anchored space let to M&S and Tesco, made up 13.8 per cent of the portfolio and returned 8.3 per cent.

Landsec (LSE: LAND) has moved the other way, selling Lakeside Retail Park in Thurrock for £114mn and Bexhill Retail Park for £70mn as part of £264mn of disposals, while buying a 92 per cent stake in Liverpool One for £490mn — a bet that dominant city-centre destinations now offer the better entry price. NewRiver REIT (LSE: NRR) and Supermarket Income REIT sit on the convenience-led side of the same trade.

Which retailers are actually expanding

Knight Frank ranked Home Bargains the fastest-growing retail park occupier in 2025 with 265 units, ahead of The Range, PureGym, B&M European Value Retail (LSE: BME) and Mountain Warehouse. Next (LSE: NXT), Marks and Spencer (LSE: MKS), Superdrug, Aldi and Lidl are all active; Lidl alone plans 19 new UK supermarkets during 2026.

M&S has been the most visible convert, opening large family-format food stores out of town, including plans to split former Homebase units with Home Bargains. Frasers Group (LSE: FRAS) uses big-box sites to pair Sports Direct with Everlast Gyms.

The Business rates twist

From 1 April 2026 England moved to a new multiplier structure. Retail, hospitality and leisure properties pay 38.2p where rateable value is below £51,000 and 43p between £51,000 and £499,999, against national multipliers of 43.2p and 48p. Properties with a rateable value of £500,000 or more pay a higher multiplier of 50.8p.

The design is meant to help smaller high street occupiers, funded by large ones. But plenty of retail park units sit in the top band, so the reform cuts both ways: cheaper small shops, dearer big boxes.

Risks to the retail park trade

Yields of 6 to 7 per cent look attractive only while gilt yields behave. Rental growth is driven by scarcity, and if planning loosens or a large operator fails, supply could return quickly. Concentration is another issue: retail parks lean heavily on discounters, gyms and food — occupiers with thin margins and full exposure to the employment cost increases hitting the rest of retail.

What happens to the high street now

Ministers announced on 11 August 2026 that vape shops will be pulled out of Class E into a standalone planning use class requiring permission, that the “aim to permit” rule for gambling premises will be revoked so councils can refuse applications, and that adult gaming centres will need planning consent from the start of 2027. Closure order powers double to 12 months.

Those measures address clustering, not demand. What high streets become is likely fewer shops and more housing, healthcare, leisure and services — a smaller retail core supported by a different mix of uses.

A relocation, not a funeral

The high street is not disappearing. It is shrinking to a size its catchment can sustain while the volume retail that used to Fill it migrates to sites with parking and lower occupancy costs. For investors, retail parks are now a supply story more than a consumer one — and supply, unlike sentiment, is slow to change.
